Be it'known that-we, BYERs W. KABEL and PERCY` R. DRENNING, citizens of the United States, residing at Baltimore city, in the State; of Maryland, have invented certain new and useful Improvements in Draft-Rigging; and we do hereby declare l said means also acting to guide the yoke and form a front stop for the forward end of the cushioning mechanism. l

The invention has'for'a further object to provide a draft rigging including in combination cooperatively associated front and back stop members connected to the draft sills, the said back stop member acting to guide the rear of the yoke and to limit rearward movement thereof beyond a predetermined position, said front stop member acting to guide the forward end of the yoke and also having a portion adapted to guide the vertical key.l

A still further object of the invention is to provide an operable connection including :Lvertical key, between the yoke andcoupler, and mea-ns including a supplemental member connected to and bridging the draft sills, saidv supplemental member acting to.

guidev the vertical key and provided with front and 'rear supplemental stops` with which said key engages upon movement of the'key beyond predetermined positions.

A still further object ofthe-invention `is 1 to provide an operable connection including a vertical key beta-'een the yoke and coupler,

' `means secured to vthe draft sills for, supporting and guiding said key, a. portionof the guiding means being; detachably` lconnected to said" sills, said detachable portion being provided with means fox-...girliding'the forwards/11d.- Of theyeke bodying .the invention.V

The present' invention Y includes among other things, ythe center or draft ysills 1-1 of the car underframe, a backstopmembel 2 arranged betwee'nfand connected to the sills bymeans of rivets 3, anda' frontor supplemental member v4 preferably formed of a one-piece or. unitaryy structureA andl adapted to bridge and be connected to the center sills by rivetsv 5. Both back stop member 2 and supplemental lmembe'r4are adapted to cooperate with a vertical yoke 6 operatively connected to the-v coupler..7 by

means of a vertical key 8, said 'supplementalv guide and limit The back stop member; 2' isf,"p-refera.billyl formed of one castinggandfis provided'with,

rea-1f stop lugs. .9.; anintermedat @html A flange or web located in the rear of said stop lugs and being provided with a buiiing face 11, a central thimble 12, and opposite side walls between which and the aforesaid the -said upright flange 10 with the side walls andtop and bottom flanges of' the casting. The'oppositely disposed side wallsare indicated b y the numeral 16, s aid walls being formed integral withthe top flange 17 -and the bottom or floor flange 18 positioned upon thecenter plate 19. Other reinforcing webs 20 may be arranged to pro- ]ect rearwardly from the central thimble, as shown.

A back stop and center sill tie casting including the forgoing associated parts is particularly adapted for use in connection with various length yokes and cushioning mecha-` nisms,`it` being obvious that the rear. follower of the cushioning mechanism, the latter being conventionallyr shown vby the diagonal dot and dash lines in Figures 1 and 2, would engage the rear stops 9 in receiving buing strains. lThe present construction o also permits of the'use. of .longer yokes whereby the said yoke'is` ada ted -to engage the buiiing face 11 when 't e cushioning mechanism becomes solid and thereby transmit .excessive buing stresses to the center sills, lthe rearward movement of said yoke.

wardly into re atively wide portions with parallel opposed faces, as shown in Figure 5, therebygproviding lateral clearance' for the' ivotal movement of the coupler key,

the ey slot' in the coupler 7 being adapted' to closely embrace the said key.-

The vertical coupler key 8 is of a length which rovides for its extending 'above and of a le than the ofthe yok; and e' ro'ecting rtions o the key are adapter? J Po ..Ibridge p y me'achanism 1s'y ngth greater,`

to be in an opening predetermined position, the

formed in4 the upper supplemental member 4, and a bifurcatc portion 24 formed in the guide member 25. The guide member 25 guides the lower end of the key 8, and is detachably connected to the center sills by means of a key 26, said last named key being adapted to pass through an opening formed in the body portion of the guide member 25 v and registering openings formed in the brackets or hangers 427 connected to the lowervanges of the center sills. The bifurcated portion of the lower guide member 24 projects forwardly and extends into a transverse support 28 which latter is connected to the lower flanges of the center-sills by means 4 of bolts 29. The support 28 forms a bearing surface for the lower edge of thecoupler key, said key being guided in the bifurcated portion ofthe member 24. The op osite.

faces of the bifurcated orfopen slottey portion are inclined or tapered in a forwardly direction and terminate'in relatively wide portions with parallel opposed faces, said inclined and parallel faces .beingI arranged reversely ofthe slots 23 provided in the yoke arms 21.

Means for guidingthe forward and lower arms of the yoke is provided n the lower guide member 25, said means including a plurality of lugs 30 having guide faces 31 (see Figures 2. and 5)'. The lugs Iare formed of a suiiicient width to extend between thelinner 'faces of the center sills and the sides. of the yoke.

, .Means for guiding the forward end of the v upper arm of the yoke is carried bythe supplemental member 4, said means consisting of lugs 32 having guidefaces 33. The lugs ioo 32 are-of a=width equal'to the lugs'30 for filling the space betweenthe inner faces of the center sills andthe sides of the yoke.

The supplemental member 4 involves the atesection 34 havingv depending ribbed vor reinforcedportions'35 adapted to be connected to the .inner faces of the center v sills by means of rivets 5, said dependlng ortions being `further connected or bridged'4 y 'means of an'integral cross member 3 6. v adafted to form 'a support for the carry iron 37,. he forward portion 38 offthe member A4 froms a striking casting, as clearly shownin Figure 2. 4The innermost portions 39 ofthe ribbed Idepending sections serve as guides for the yoke, and the vertical faces 40 of said-depending sections act as :front stops with which'the vforward follower of.V .the cushioning mechanism engag An integral housing 41 is provided inthe member 4, said housing having a groove or yslot 42 adapted to receive. the upper end of the coupler key, and front and rear walls 43 and- 44 adapted to form forward and rearv supplemental stops for said key upon movement thereof in'. either -direction beyond a' respective ',tically alined with the front stop 43 whereby forward movement of said key is arrested,

beyond a predetermined point. A rear stop 46 is also provided for the lower rear edge of the coupler key upon 'movement beyond a predetermined position, said rear stop being the end wall of the bifurcated or slotted portion in the detachable lower guide member 24 and being further vertically alined 'with the rear wall or stop 44 provided on the top bridge portion of lthe supplemental member. 1

r1`he supplemental member 4 is strengthcned by a series of webs or flanges adapted to directly reinfor e the front and rear wallsof the housing 41 againstwhich walls the respective edges of the coupler key are designed to abut. A series of radiating webs 47 is provided for the front wall, and a series of similar flanges or webs is provided for the rear wall. Laterally extending webs 48 are provided at the rear of the place sections, one of said webs intersecting the rear wall of the housing, the other of said webs constituting an upturned flange at the rear of the top bridge portion.

The relative association of front and rear stops for the cushioning mechanism arranged within a vertical yoke, and the construction of the supplemental .bridge and supporting casting carried by the center sills and adapted to effectively y guide and limit the respective forward and rearward movements of the vertical key connecting the yoke and coupler, constitutes a particularly adaptable draft rigging which can be easily installed and economically maintained.
